I'm starting to make some CS:GO custom paint style weapon finishes with SD4. I can paint on the UV sheets and view it on the models with no problem, but what i'm trying to do, is to use the alpha masking feature that is used in the game, by using the alpha channel to reveal some of the original texture of the weapon in-game.
Problem i'm having is i can't find any alpha amount control, to apply the certain amount of alpha to the alpha channel, which when i load my weapon finish into the game, it'll remove the parts of my texture with the certain alpha to show the original texture.
I've used the opacity slider which changes the amount of alpha, 77% gives the 196 alpha i need, but i need to do a continuous paint as it changes the alpha amount if i paint over it again. What i'm only looking for is to either keep hold of a fixed amount, or get the alpha channel seperate from my painting areas.
Here are links to the CS:GO workshop weapon finishes guide on Steam, to better explain what i'm trying to get:
